    // Presentation :
    //     PclZip is a PHP library that manage ZIP archives.
    //     So far tests show that archives generated by PclZip are readable by
    //     WinZip application and other tools.
    //
    // Description :
    //     See readme.txt and http://www.phpconcept.net

        //     filesystem. The files and directories indicated in $p_filelist
        //     are added in the archive. See the parameters description for the
        //     supported format of $p_filelist.
        //     When a directory is in the list, the directory and its content is added
        //     in the archive.
        //     In this synopsis, the function takes an optional variable list of
        //     options. See bellow the supported options.

        //     $p_filelist : An array containing file or directory names, or
        //                                 a string containing one filename or one directory name, or

        //                                 names separated by spaces.
        //     $p_add_dir : A path to add before the real path of the archived file,
        //                                in order to have it memorized in the archive.
        //     $p_remove_dir : A path to remove from the real path of the file to archive,
        //                                     in order to have a shorter path memorized in the archive.

        //                                in order to have it memorized in the archive.
        //     $p_remove_dir : A path to remove from the real path of the file to archive,
        //                                     in order to have a shorter path memorized in the archive.
